You can get phi=0, or other phi values. But I do not think  it is the same as the 2D plane you want. Please test and compare the results: directly do the 2D and extract 2D data from 3D.

One more thing to think: polar plot requires angles from 0 to 360. But theta is from -90 to 90 deg for a given phi, how can you plot it in polar?
